Part Number:BEAGLEBN
Tool/software: Linux
Hi,
I have a BBB flashed with the Arago pre-built image that comes with SDK Linux 05_01_00_11.
I have attached a USB sound card. It is correctly detected and I can play wav files with 'aplay'.
Now I am trying with pjsip application and audio is not working. Pjsip comes with a simple test application called 'playfile', which simply plays a wav file. This application is not working either. Doing some debugging, I have seen that, after calling 'snd_pcm_writei' a few times, then it never returns. So, I guess there is some problem with DMA or something similar, to transmit audio samples to the USB device.
Any ideas of where the problem could be? Does the pre-built image of this SDK support USB sound cards?
Best Regards,
Miguel
